The GNU autoconf support for ACE and TAO should work fine
"out-of-the-box."  The autoconf support for CIAO is not yet complete,
so we recommend avoiding it and using the alternative build mechanism.
We are interested in getting help to finish CIAO autoconf support so
it you want to help us improve CIAO's autoconf support please contact
<A

Naturally, if you run into problems with the use of autoconf in ACE
and TAO please submit submit a <A

report</A>.
